PROJECT TITLE :

A capacitance study of anomalous diffusion of water into HTV silicone rubber materials

ABSTRACT:

Capacitance and gravimetric measurements are used to check the diffusion of water into heat vulcanized (HTV) silicone rubber. Silicone rubber with completely different Alumina Tri-hydrate (ATH) filler contents was utilized in this analysis, and deviations from the classical Fickian diffusion were observed. A model is presented for the calculation of the diffusion coefficient of water in silicone rubber by capacitance methodology in that the anomalous diffusion mechanism and the water concentration profile are thought of. The present model is compared to different models and also the distinction between the diffusion coefficients obtained is analyzed.
